To aLnWHoM/I'r MAY coNcERN:

e it known that I, JOSEPH NOTTINGHAM SMITH, of Jersey City, in the county of Hudsoma'nd State of New Jersey, have invented'certain Improvements in Hydrants; and'I do hereby declare that `the following is a v 'full and exact description thereof, reference being-had to the accompanying drawings, making part ofVt-hisspecicati'ni f l Figure v1 -being a central vertical section of the lower part of a hydrantprovded with ,my improvements, `Figure 2, .a transverse section of one part in aplane indicated bythe-line 1:,Ig. 1. I I

vFigure 3,- a transverse section of the body or case. Figure 4, a top view of the valve-sentand'valve.

Like lcttersdcsignatc corresponding parts in all of the figures. I make the hydrant body, or case A, of boiler-plateor thick sheet metal, simply-bent round into vcylindrical form, and bound' just below the surface of the 'ground with a hoop, a. This makesa cheaper body and less liable to damage from violence or frost than a cast-ironbody. 'The'lower end of the-body is attachedby screws b t, or otherwise, toa cast'iron base, B, which is buried beneath the'surface of 'the ground, and has'a chamber,

C, below, that receives the waterpipe c. The chamber. C isclosed at top by a tubular valve, ,ha-ving an annular flange, g, which is pressed upward against an inverted, 'cup-shaped seat, D, both bythe pressure of the water and-by an annular India-rubber spring, G, which also" may serve as apacking to prevent the escape of water below and outside of the valve, all substantially as shownninfig. 1. But other kinds of springs (as coiled springs) may beused instead of the India-rubber spring G, and other'means of packingmay be employed. Thevvalve-seat D maybe held in place by a central` rod, d, projecting upward from the base 'below and holding' the cup-seat by a screw, e, substantially as shown. 'By this Screw the position of the valveseat may be adjusted; and it maybe removed readily to get at the valve'below. The valve has anv annular, leather, co`rk, India-rubber,

or other equivalent material of packing, f, resting upon its upper sur'face,'and'pressed upward -algai-nst the lower annular edge 7; ofthe' valve-seat D, ,by which the water is excluded from passing upward unless thel Jwater is lowered away from the valveseah The 'central tubular portion of the valve extends some distance above its packingfinto the inverted cup-shaped seat D and the upper ,edge of this tubular portion (throughwhich the water all passes) is covered by a wire-gauze (or perforated).partition, I, so as to form a strainer, to prevent all obstructions from going up into the hydrant,iand`to exclude any insects, fishes, or other vermin thatinay chance to get into the water pipe, so as neither to c01'ne`out at the hydrant nor get into it', and, dying there, render it foul. A nd if thcreshonld ever be accumulated in the chamber C'any impurities whatever` the `hydrant is so constructed in all`its parts that accessv can readily behad thereto -to .clean itout. This is an important feature; in thev hydrant.'- The' strainer I s stretched down over the At'op' of the valve and is h eldrin its -placebeneath the packingf. It can readily be removed and renewed.v :Thief-waiter, after passing through the valve, enters a filter-f tubc'or chamber, L, the lower edge l of which rests on the valve F, and is packed thereby so as to prevent the escape ofvwa'ter 'outsideiof it. In the upper part of this chamber I place suitable filterin'gmaterial or 'materials y to'purify all'the water coming from the hydrant. The top N of the chamber isperforated 'to'.allow the water to pass, and a perforated, removable bottom, M, is inserted below the filtering material so as toallow facilities for removing and renewing the filtering material. This -bottom is h eld in place by'projections 'm m from the inner surface of theehamber L, on which it rests, and by which itcan pass on bringing corresponding notches" n n (E152) in `its edge-opposite to the projections. 'Above and around the filter-chamber I4, a plunger-cap,fR, is located, substantially as represented, the discharge pipe S being attached to t-at the top by a scew,'s,or otherwise. This -plunger-cap is large enough to allow a free circulation ofwater up and down around the llte'r'i chamber. Its -lower end terminates -inabroad projecting flange, @substantially ofthe f or'm shown; and a similar, broader flange, o, projects outward from the lter-bhamber'L below, substantially as and ofthe form shown. To those two flanges, respectively, the two v ends of a short tube, Q, ofv India rnbber oro t hei suitable eiiblcmaterial, are secured water-tight,- the attachment being well eiected by means of twometallic cupa-P and T, respectively secured to the flanges o and. r by'screis pp and t t so as to clamp the ends of .tllfczlle-xib'le tube between them, all substantially as'shown in 1. 'These caps serve as guids to the flexible t'ubeQ, .v v`i'ch forms a frictionl'css, perfectly tight packing or eniclosingvjoint for the reservoir between the langesb'and 1".

There is eucient room between the cups P and 'l tov allowthe tube Q to double ifreely' at any part when the plunger moves up anddowp. Y I .l

Thus constructed, the working of the hydrant is'obvious, being effected by moving the discharge-pipe Sand plunger R down and up by means of any suitable device at the top'ot` the hydrant. A s the plunger is forced down, first the water which is in the reservoir, between the flanges o and r, is nearly all forced up into the dischargeI pipe. Then the plunger strikes the top of the filter-tube l, which rests ou the valve F, so`tliat,a's the plunger continues to descend, it causes the filtertube to depress the valv'e F and allow the water to flow", then, on raising the plunger, the valve is forced bythe pressure b'elow'up t`o its'seat and stops the flow of water and the furtherlrise of the plunger 4(muses the reservoir's space between the flanges o and 'r to enlarge 'and receive all the surplus water from thedischarge pipe S, there to beretained beneath the surface of theground, out of the way of the e'ect of the sun and frost'. V' Y What I vclaim asmy invention, and desire to secure by Letters Patent; is

The tubularfilanged valve F, operating'substantially as' herein specified. Y

I'also cluim the in rei-ted, cup-shaped valve-seatvD, in combination 'with the valve F,7substantially as herein described. O v v A I l I also claim the filter L y, arran Y I also `clainz thecombination of thefilter,tube L, with the valve F, substantially as and for the purpose hereinset forth.,` I E,

I also claim the flexiblepacking Q, iu combination with the cups Pand T', substantially in .the manner and for thepurpose herein specified.' o

The above specification of my improved hydrant signed by me this day ofA October, 1866. Jl VNoilrTINGHM/I SMITH.
